ROADWAY.

Specification of Letters Patent.

Application led May 8, 1919. Serial No. 295,58.

T 0 all whom t may concern.'

Be it known that I, ANTON ANFINsoN, a citizen of the United States, anda resident of l/Vakonda, in the county of Clay and State of SouthDakota, have invented certain new and useful Improvements` in Roadways,of which the following is a specification.

My invention is an improvement in road ways, and has for its object toprovide mechanism for use in connection with ordinary country highways,for lconverting said highways at small expense and in a minimum of timeinto metaled road ways, to provide relatively narrow tracks of plasticmaterial capable of hardening, such for instance as concrete.

In the drawings:

Figure l is a plan view showing an arrangement of double track,

Fig. 2 is a similar view showing an arrangement of single track,

Figs. 3 and'6 are sections on the lines 3--3 and 6 6 of 1,

Fig. 4 is a section on the line i-b4 of Fig. 2,

Fig. 5 is an enlarged section of one of the track ways.

In the embodiment of the invention shown in Fig. 1 the road way l whichis crowned or arranged transversely in the usual manner, and providedwith the drainage ditches or gutters 2 at each side as at the center ofthe crown thereof four relatively narrow track ways 3.' These track waysare spaced apart from each other a distance correspondingto the standardgage of the vehicles, so that the wheels of a vehicle may run upon twoadjacent track ways to support said wheels out of contact with the soil.

In the present instance the spacing of the four track ways is the same,so that a vehicle may run upon any two adjacent track ways. It isobvious however that thc two pairs of track ways might be spaced closcrtogether or farther apart if desired.

At road crossings the adjacent track ways of the intersecting roads havetheir adjacent sides connected by curving lines 4, and the entire spacebetween these four lines 4 is paved with concrete indicated at 5. Thusthe four tracks of the two intersecting roads are practicallycontinuous. A vehicle for instance on the two right hand tracks of Fig.1 moving toward'the bottom of the sheet may turn curvingly on to the tworight tracks at the left of the sheet. Since only enough concrete isused to make a relatively narrow track way for each wheel, except atroad intersections it will be obvious that the cost of a road wayconstructed in accordance with the invention will be very much less thanwere it necessary to pave the entire width of the ltread portion of theroad.

In Fig. 2 is shown a single track arrangement, each road way having twotracks 6 properly spaced with respect to eachother. At roadintersections the four relatively narrow track Ways are connectedl bythe paving 7 which is of approximately square outline, having howeverits sides concave. g

Referring to Fig. l6 it will be observed thatA the upper face of eachtrack way is concave, that is it is hollowed outor guttered from side toside to provide trough shaped depression 8 in the othervsurface 'of thetrack way. This assists in retaining the wheels in the track way. Eachtrack way may be reinforced in any suitable manner, as for instance byseries of reinforcing rods 9 which are arranged transversely of thetrack way at suitable intervals, and also by longitudinally extendingreinforcing rods 10, any suitable numbery and arrangement being used. Inpractice expansion joints will be provided, the said joints beingarranged at desired intervals, as for instance every 50 to 100 ft.according to locality and to the usage to which the road will beexposed.

The improved road way will accommodate not only motor vehicles, buthorse drawn vehicles as well, and is especially adapted for the use ofhorses, since the horse has the path way of soil on which to As* isknown, hard pavements are very trying on the hoofs of horses. -With thepresent construction the horse travels on the ground.

With the single track construction,i suitable passing points might beprovided if desired, in the nature of switches. It will be obvious thatwhile al firm and solid wheel base is provided, the expense will be muchless, both for material and labor than where the entire road Way is`made solidly conspaced parallel bodies of plastic material crete.embedded Within the ground and each con- I claim: caved at its upperface in cross section, and 10 In combination, a plurality of trackways asmooth pavement connecting the ends of 5 arranged in intersectingrelation and terthe trackways.

minating short of actual intersection, each trackway being formed of aplurality of ANTON ANFINSON.
